Caution

If you have any of the following conditions / risk factors, you should weigh the benefits of using gestagen and the possible risks for each individual woman. This should be discussed with the woman before she decides to start taking the drug. In the event of a worsening, exacerbation of the disease or the occurrence of any of these conditions, a woman should first consult a doctor. The doctor should decide on the appropriateness of further use of the Charozet drug):

Persistent hypertension that develops while taking the Charozet drug, or with ineffective antihypertensive therapy.

Thromboembolic disorders, including a history of: a woman should be warned about the possibility of relapse.

Prolonged immobilization associated with surgery or disease.

Since it is impossible to exclude the biological effect of gestagens on the development of liver cancer, an individual assessment of the benefit-risk ratio should be made when prescribing the drug to women with liver cancer.

Chloasma, especially in women with a history of chloasma during pregnancy: women with a predisposition to chloasma should avoid exposure to sunlight or ultraviolet radiation while using Charozet.

Use during pregnancy and lactation

During pregnancy, the use of the drug is contraindicated. Preclinical studies have shown that very high doses of gestagens can cause masculinization of the female fetus. Extensive epidemiological studies have revealed neither an increased risk of birth defects in children whose mothers took oral contraceptives before pregnancy, nor a teratogenic effect in case of unintentional use of oral contraceptives in early pregnancy.

The drug does not affect the quantity or quality (concentration of protein, lactose or fat) of breast milk. However, Small amounts of etonogestrel are excreted in breast milk. As a result, 0.01-0.05 micrograms of etonogestrel per kg of body weight per day can be delivered to the child (based on consumption of 150 ml / kg / day of breast milk).

There is limited evidence for long-term follow-up of children whose mothers started taking Charozet within 4-8 weeks after giving birth. The duration of breastfeeding was 7 months, and the children were monitored until they reached the age of 1.5 (n = 32) or 2.5 years (n = 14). Assessment of growth, physical and psychomotor development did not reveal any differences with babies whose mothers used copper intrauterine devices. Available data say that Charozetta can be used during lactation. Nonetheless, it is necessary to carefully monitor the development and growth of the infant, whose mother uses the drug Charozetta.

However, if a woman had already had sexual intercourse after giving birth or abortion before taking Charozet, she should be excluded from pregnancy or the woman should wait for her first menstruation.

What to do if you miss the next pill: contraceptive protection may decrease, if the interval between taking two tablets is more than 36 hours. If the delay in taking the pill is less than 12 hours, then the missed pill should be taken immediately as soon as the woman remembers this, and the next pill should be taken at the usual time.

If vomiting occurs within 3-4 hours after administration, then absorption may not be complete. In this case, it is necessary to be guided by the recommendations regarding the intake of missed tablets.

Drug Interaction

Interaction between oral contraceptives and other drugs may lead to breakthrough bleeding and / or decreased contraceptive efficacy. The following interactions have been reported in the literature (mainly with combination contraceptives, but sometimes also with respect to gestagen-containing contraceptives).

Hepatic metabolism: interactions with drugs that induce microsomal enzymes may occur, leading to increased clearance of sex hormones (eg, hydantoins (eg, phenytoin)), barbiturates (eg, phenobarbital), primidone, carbamazepine rifampicin and probably also oxcarbazepine, rifabutin, topiramate, felbamate, ritonavir, nelfinavir, griseofulvin and preparations containing St. John's wort (Hypericum perforatum).

Women taking any of these medicines should temporarily use the barrier method in addition to the Charozetta drug or choose another method of contraception. The barrier method of contraception should be used during the administration of these drugs and within 28 days after discontinuation of their medication. For women receiving long-term treatment with hepatic enzyme inducers, the use of a non-hormonal method of contraception should be considered.

When using activated charcoal, the absorption of desogestrel contained in the tablet may be reduced and therefore contraceptive efficacy may be reduced. In this case, follow the recommendations for missed tablets.

Hormonal contraceptives can affect the metabolism of other medicines. Accordingly, the concentrations of the drug in plasma and in the tissues can both increase (eg, cyclosporine) and decrease.

To identify possible interactions, read the instructions for use of these drugs.
